Beneficial or Detrimental

Cars in the shop getting painted and I'm getting things together for when it returns home. I have the rear glass all cleaned and polished ready to go when the time comes, would it be beneficial (except to protect the glass) or detrimental to install the weatherstripping (with the sealant) on the glass? I'll probably have someone with some experience install the glass.
 
Let the installer do it. Otherwise if it leaks, he'll point his finger to whoever installed the weather stripping.

Is it more important that you have someone to blame if it leaks, or to make sure it doesn't leak?

I chose to mount the gasket on my glass (including loads of sealer) before the installer showed up. I also applied the sealer to the frame and weatherstrip groove. I also installed the cord for pulling the gasket through. I couldn't control what he did, but I could make sure there was enough goop in there when they actually set the glass.

There are fewer and fewer glass guys around who know how to properly set vintage Mustang glass. I had never done it before, but researched it enough to know what needed to be done. I wanted to minimize the chances of leaks by doing what I could before they showed up.

They arrived and basically said, "There's nothing for us to do - you did all the work." They set the glass and were gone in 15 minutes. They didn't even charge me.

If you're not sure where and how much and so forth, then you should leave it to your glass guy. If you do know where and how much and so forth, they you have to decide the answer to my first question.
 
I had the same question too. It's not like it's hard....just messy. Although if you run painters tape around it after you install the gasket, the cleanup is much easier!

I've done it both ways.

If I'm re-installing the OLD glass I removed, I'll do it myself, but it's a LOT easier having someone press downward/inward on the glass while a second person is inside the car pulling the cord.

If I order a NEW glass the price of the glass is only a few dollars more to have someone else install it. I'll pay the extra ~$50 if for nothing else than an "insurance policy" in case the glass cracks while pressing it in.

That's fair. It's because I'd never done it before and wasn't absolutely sure I knew "the trick". I wanted someone experienced on the job. Once I saw them do it, I realized I could have done it. Just didn't want to risk messing it up.

Also to the OP - I've read horror stories about glass men using the wrong compound, too. There's only one correct product, and it's 3M Bedding and Glazing Compound. I knew that and got some. If you decide to let a pro do it, make sure he knows, too, and agrees to use it. Or better yet, have a coupla tubes on hand and make him use yours.
 
You have a '70 Mach I, right? Therefore, I'm assuming you're only talking the BACK glass. The front glass doesn't have a seal. It uses mastic as the seal, and is glued in with that, much like modern windshields.
